+//! iOS support
+//!
+//! # Building app
+//! To build ios app you will need rustc built for this targets:
+//!
+//! - armv7-apple-ios
+//! - armv7s-apple-ios
+//! - i386-apple-ios
+//! - aarch64-apple-ios
+//! - x86_64-apple-ios
+//!
+//! Then
+//!
+//! ```
+//! cargo build --target=...
+//! ```
+//! The simplest way to integrate your app into xcode environment is to build it
+//! as a static library. Wrap your main function and export it.
+//!
+//! ```rust, ignore
+//! #[no_mangle]
+//! pub extern fn start_glutin_app() {
+//! start_inner()
+//! }
+//!
+//! fn start_inner() {
+//! ...
+//! }
+//!
+//! ```
+//!
+//! Compile project and then drag resulting .a into Xcode project. Add glutin.h to xcode.
+//!
+//! ```c
+//! void start_glutin_app();
+//! ```
+//!
+//! Use start_glutin_app inside your xcode's main function.
+//!
+//!
+//! # App lifecycle and events
+//!
+//! iOS environment is very different from other platforms and you must be very
+//! careful with it's events. Familiarize yourself with [app lifecycle](https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/).
+//!
+//!
+//! This is how those event are represented in glutin:
+//!
+//! - applicationDidBecomeActive is Focused(true)
+//! - applicationWillResignActive is Focused(false)
+//! - applicationDidEnterBackground is Suspended(true)
+//! - applicationWillEnterForeground is Suspended(false)
+//! - applicationWillTerminate is Closed
+//!
+//! Keep in mind that after Closed event is received every attempt to draw with opengl will result in segfault.
+//!
+//! Also note that app will not receive Closed event if suspended, it will be SIGKILL'ed
